摘要(Abstract)：

针对现代停车场的用户"找车难"问题,基于可见光通信技术给出了一套系统应用方案。系统将可见光通信技术应用于停车场场景,并实现了车辆精确定位、反向查找和实时路径引导等功能。系统中的信号调制方法选择连续相位的二进制频移键控(2FSK)。比较于光信号传输中惯用的强度调制/直接探测的通信体制,系统的调制方法选用了相干解调,有效提高了通信灵敏度,降低了误码率。该系统支持用户手持共享接收器读取身边的地灯位置信息到手机上,结合移动应用程序完成导航。本研究为停车场的定位管理及发展提供了一种思路和参考。
Aiming at the difficult problems of finding vehicles in modern parking lots,this paper presents an application scheme based on visible light communication. Visible light communication technology is applied for the parking lots to realize precise location,reverse search and real-time path guidance. 2 FSKS with continuous phase has been introduced in signal modulation in the system. Comparing with the IM/DD( Intensity modulation/direct detection) in optical signal transmission,the modulation method of the system adopts the coherent demodulation,which improves the communication sensitivity and reduces the BER( Bit Error Rate). The system supports the user' s hand-held sharing receiver to read the locations of the ground lights which are transmitted to the mobile phones,and completes the navigation with the mobile application.The study of this paper provides a kind of thinking and reference for the location management and development of parking lot.
